一般人都认为一天中正午时最热,其实并非如此。每天日出后,随着太阳高度角的增加,太阳辐射不断增强,地面温度不断上升,地面辐射逐渐增强,气温不断上升。正午12点时,太阳辐射最强,地面吸收的太阳能最多,但地面储存的热量并没有达到饱和,所以这时地面温度未达最高点。12点过后,虽然太阳辐射减弱,但地面仍在继续吸收太阳辐射能量,所以地面温度仍在上升。在下午2点左右时,地面
Most people think that the hottest day at noon, in fact, not the case. After the sunrise every day, with the increase of the sun’s elevation angle, the solar radiation continues to increase, the ground temperature keeps rising, the ground radiation gradually increases and the temperature keeps rising. At 12 noon, the solar radiation is the strongest, the ground absorbs the most solar energy, but the heat stored on the ground does not reach saturation, so the ground temperature has not reached the highest point at this time. After 12 o’clock, although the solar radiation weakened, but the ground continues to absorb the solar radiation energy, so the ground temperature is still rising. At about 2 o’clock in the afternoon, the ground
